“…The YD/PB transition was dynamic not only because of the rather rapidly rising air temperature but also because of the accompanying changes in the natural environment (degradation of permafrost, including the melting of the buried lumps of dead ice, or, for example the migration of vegetation from southern refugia). This contributed to the unstable and nonunidirectional nature of the changes (Płóciennik et al, 2022;Słowiński, 2010).…”

“…More to the east, in the Romanian part of the Carpathian Mountains, a decrease of about 0.7°C was reconstructed in Lake Brazi for a comparable period, 11,480–11,390 cal BP (Tóth et al, 2012). A decrease in temperature was also recorded in a profile from Lake Gościąż in Poland, based on Chironomidae analyses (Müller et al, 2021; Płóciennik et al, 2022). Such significant climate changes had an influence on the transformation of the vegetation cover, and have been recorded in many palynological profiles in Northwest Europe, Iceland, or Greenland.…”

“…In central Europe, the beginning of the Holocene was marked by dynamic changes in the natural environment, which were primarily associated with climate warming (Bakke et al, 2009; Brauer et al, 2008; North Greenland Ice Core Project members, 2004; Płóciennik et al, 2022) and accompanied by increased migration of vegetation from southern refugia, as well as changes resulting from the final disappearance of permafrost (Brauer et al, 1999; Błaszkiewicz, 2005; Pazdur et al, 1995; Słowiński et al, 2015). All these changes are responsible for the highly dynamic and unstable nature of the Preboreal period at various spatial scales.…”

In this work, we studied the course of climatic fluctuations at the beginning of the Preboreal period using multiproxy analyses (Chironomidae, pollen, diatoms, Cladocera, stable isotopes, macrocharcoal, microlithofacial) combined with varve chronology of sediments. The results showed a decrease in the mean July temperature and stronger continentalism followed by climate wetting at the start of the Preboreal period. This was reflected in the remodeling of the vegetation cover from birch forests to more open spaces with grass vegetation dominance, as well as that of the species composition of Cladocera and diatoms, and the high variability of isotopic composition. In addition, the results showed the impact of local conditions (fires and relict permafrost) on the amplification of environmental responses due to climate cooling. The environmental transformations presented here correspond temporally to the changes that are well documented in other parts of Europe as the Preboreal Oscillation.

“…Sometimes it is difficult to explain Chironomidae disappearance during interglacials that are warmer and reveal higher production in lakes. In deeper lakes, rising summer temperatures may induce stratification, which is unfavourable for benthic organisms in the profundal zone (Jyväsjärvi, Hämäläinen 2014;Płóciennik et al 2022). Eemian sequences often evince low midge head capsule counts (Plikk et al 2019;Bolland et al 2021;Polkowski et al in preparation).…”

In the end of Saalian Glaciation (Wartanian Stadial, MIS 6a) there formed many glacial depressions, melt-out kettle holes and subglacial channels in central Poland's ice-marginal zone. In these landforms, there developed a lakeland that existed to the Early Weichselian (5d-a). Following excavation in 2016 on the eastern wall of the Szczerców field, lacustrine deposits were recognised in the Parchliny 2016 profile. A previous multi-proxy study of the Parchliny 2016 profile concerning a reconstruction of the palaeolake included analyses of pollen, plant macrofossils, wood macrofossils, diatoms, cladocerans, ostracods and molluscs. The present work presents the Chironomidae analysis for the above-mentioned section. The collected subfossils could be identified from the keys presenting modern Palaearctic fauna. The Chironomidae indicate a temperate climate in the region and favourable, meso/eutrophic conditions in the palaeolake during the Late Saalian (MIS 6a). The changes in subfossil numbers reveal that the Zeifen interstadial fells at 24.38-24.23 m core depth and the subsequent Kattegat stadial at 24.18--23.83 m, but head capsule count is too low for quantitative temperature estimations. From the Eemian (MIS 5e) transition, they decline in the sediment and are represented only by two head capsules at the 23.33 m core depth below the ground surface. The increase in summer temperature, trophic status and stratification of the lake may have caused an oxygen depletion that eliminated sensitive taxa. However, no species are observed that are resistant to eutrophication and anoxia replacing sensitive ones in the assemblages. Sediment desiccation and compaction may have caused the decomposition of Chironomidae subfossils in the deposits from the Eemian interglacial, so their apparent decline in the ecosystem may be misleading.

The Younger Dryas-Holocene transition represents a period of significant thermal change, comparable in magnitude to modern warming, yet in a colder context and without the effect of anthropogenic disturbance. This is useful as a reference to tackle how biodiversity is affected by temperature in natural conditions. Here, we addressed the thermal change during this period in a southern Baltic coastal lake (Konarzewo Lake, Poland), as inferred by chironomid remains. We evaluated changes in chironomid communities and used Hill numbers to explore how commonness and rarity underlie biodiversity changes attributable to warming. We found evidence of warming at Konarzewo Lake during the Younger Dryas-Holocene transition, with inferred temperatures in the Younger Dryas period supporting the NW–SE gradient in Younger Dryas summer temperatures across Europe. Chironomid communities drastically changed during the thermal transition. However, Hill numbers showed no response to temperature when rare morphotypes were emphasized (order q = 0) or a weak response when they were balanced with common morphotypes (order q = 1). Hill number of order q = 2, emphasizing the most common morphotypes, consistently increased with temperature across different sample sizes or coverages. This illustrates how common morphotypes, rather than the rare ones, may boost biodiversity facing warming.
